Upfitter Switch installation

[billp9]

You're welcome. I sure use mine a lot. It is alway more satisfying and fun making this yourself.
Glad to help. If you run in any problems let me know and I will try to help you.

Please post some more details on the harness part. 2024+ owners want this and apparently it’s different than the 2021-2023.

I figured out the illumination. The culprit was my ground wire.

Thanks @billp9… just want to clarify some things from the write up that worked for me:
Upfitter switch pin … relay pin
9 … fuse 2 (hot in/acc delay) … 12
1 … 5

for illumination
11 … overhead (c930) tap violet/gray wire
6 … overhead (c930) tap black/yellow wire — pin 1 on the relay connector also needs to be grounded

Switches are getting both blue and amber illumination. Now I just have to make sure power is getting to the relay output wires.

Is this how you ended up wiring it? Wire tapping a solid wire from 9…12 with the add a fuse in between?
and for pin 6 from the overhead console, go from that to a wire tap down by the BCM on a black/yellow wire, and not connected to the relay box, but the relay box 1 goes to a ground bolt connection.

Okay, I got it figured out a couple weeks ago. (Follow these instructions at your own risk)
T-Tapped both the purple/gray for illumination and black/yellow for ground from the connector on the front of the overhead console. (I first t-tapped a grey/purple wire and the lights only stayed on when the door was open, so make sure it’s purple with a small grayish white stripe)
Then T-Tapped the add a fuse into the wire going from overhead #9 to relay box #12.
I built the wire harness beforehand on the overhead console side and the pins are very finicky on the plug, so be careful with those and buy extra. I kept the relay box connector undone and electrical taped the wire ends to route the harness through the interior.
Followed the instructions from boosted listed earlier in this thread to hook up the relay box, and zip tied it to the positive battery cable. Also used it to route the wire, but didn’t remove the seat and went through the grommet below the passenger footwell in-front of the seat.

So far I have added Baja Designs Squadrons for ditch lights, but more too come…
